ToryCMS-ExtBM is a Chrome extension for granting Admin access to Facebook Business Managers in bulk. Paste an access token and the full BM list loads — ad account count, user count, and status included; tick the BMs you need and share them with a recipient email in a single action. Pick BMs from the table or paste a list of IDs directly, set a delay between sends, and watch results split into success / failure right on screen. Vietnamese and English interface, free to use, no sign-up required.
